Patented Sept. 9, 1913.

Application led September 18, 1905. Serial No. 278,847.

Figure l is a plan View with cover revmoved ot' a battery embodying my invention; Fig. 2 is a sectional view taken on line 2 2 of Fig. l, with cover in position; Fig. 3 is a sectional View taken on line 3 3 of Fig. l; Fig. 4 isa view showing a modiiied construction.

Like letters refer to like the several figures. f

Referring now to Figs. l, 2 and 3, have shown an electric batteiycomprising a suitable receptacle, A. Nithin this receptacle are located the two electrodes of the battery,

parts throughout B and C. The electrode B as herein shown is made of carbon, and the elect-rode C of Zinc.v In these figures l have shown two' carbon plates. The ends of vthe carbon plates project through the receptacle and are electrically connected together in any desired manner, as by the bolts B1. The two ends of these carbon plates are electrically connected together by the conductors B2. One conductor may be used if desired because of the fact that the two carbone are electrically connected together at the ends. The exposed ends of the carbon plates are preferably copper plated so as to prevent the fluid of the battery from escaping through the pores thereof, and will also aid in making proper electrical contact. The zinc electrode C is placed between the two carbon plates. Suitable partitions D are preferably provided, and the space between these partitions and the receptacle is filled with paraffin or other material as shown at DH rI'he bottom of the receptacle is also 'covered with paraiiin as shown at D2, Fig.

3, the carbon plates projecting into the parailin so as to separate thel receptacle into compartments. The active material is placed in thespace E andthe depolarizing material in the spaces F. The zinc is provided with a suitable binding postk C1 and the carbone with a suitable binding post B3. A ysuitable cover G is provided for the battery. As illustrated in Fig. 4 the ca'cbonsv do not proj ect through the receptacle but lare contained' entirely within it.` The conductor B2 which connects the 4ends of the car-v bon together preferably pass along the top` ofl the battery as shown." Itwill be seen that byV means of this construction very large electrodes can kbe used, and thus a large carrying surface isy provided and an eiilective and economical battery produced.

Vl have shown in detail particular con- Y structions embodying my invention,butit 1s, of course, evident that the torni, construction and arrangement of the battery may be varied in many particulars, and l, therefore,

do not limit myself to the particular: constructions shown. Y

I claim.

l. An electric battery comprising a re- ,s ceptacle a positive electrode therein,` .two

`carbon electrodes therein, both ends of each Y of said electrodes proj ecting-through the receptacle, the associated projecting ends electrically connected together, the separated ends of each electrode electrically connected together by an electrical conductorseparate from the electrode.

2. An electric battery comprising a rc'- ceptac'le,a"positive electrodeA therein, two

Vcarbon electrodes therein, both ends of each of said electrodes projecting through the receptacle, a separate conductor by which the `associated projecting ends are electrically connected together, the separated ends of each electrode connected together by an' electrical conductor, and a layer oiprotecting material on t-he inside of the receptacle at the points where the electrodes proj ect therethrough. I

3. An electric battery comprising'a reeptacle,`two carbon electrodes therein, vsaid receptacle provided with openings, the ends of both of said electrodes projecting through said openings, bolts at the ends of said electrodes and outside oic said receptacle, said bolts connecting said ends together.,
